Turbochargers are great for coaxing more power and better fuel economy out of smaller engines. However, they’re exposed to exhaust gases as hot as 1,000ºF and can spin up to 150,000 rpm, which can lead to bearing deposits – known as turbo coking. To keep your turbocharged engine running strong, use a high-quality synthetic oil proven to protect against high-temp turbo deposits.
